Cool!- I was only concerned about the action itself coming off face, not the barrels themselves.
; Many line jobs, eliminate the original barrels ahead of the breech-stubs anyway. Many double's smooth barrels are sweated into the breech stubs. A while back, one of the fellows did a photo expose' on the .450#2 Express he built on a double rifle & the regulations wedges he planted in the middle and at the muzzles prior to sweating on the ribs.
